February 15, 2024 CISA ICS Advisory

Summary

Parasolid is affected by out of bounds read and null pointer dereference vulnerabilities that could be triggered when the application reads files in XT format. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process. Siemens has released new versions for the affected products and recommends to update to the latest versions. CVE-2023-49125: The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted files containing XT format. This could allow an attacker to execute code in the context of the current process. CVE-2024-22043: The affected applications contain a null pointer dereference vulnerability while parsing specially crafted XT files. An attacker could leverage this vulnerability to crash the application causing denial of service condition.
